Abstract
An IV pump for delivering fluid through a resilient, deformable tube to improve the accuracy, consistency, and predictability of flow through the tube, wherein a plurality of pinching fingers occlude the tube against a flat portion of a pressure pad, and a plurality of pumping fingers interspaced between said pinching fingers deform the tube (without occluding it) from different directions against a V-shaped portion of the pressure pad to pump the fluid downstream as well as to urge the tube to restore its cross-sectional area.
